# Chat appears down

It appears Chat is down:

• Seems up again, if anybody else experienced chat issues please comment below. – Maarten - reinstate Monica Oct 1 at 12:31
• Works for me. Is it still broken for anyone else? – Squeamish Ossifrage Oct 1 at 13:14
• Note that there seems to be some hidden characters behind the URL in the picture. Not sure what it says, but it could have something to do with the error. – Maarten - reinstate Monica Oct 1 at 13:55
• Chat works for me too – Ella Rose Oct 1 at 14:21
• The URL in the screenshot is wrong. There is no specific chat instance for crypto SE. There is only one on chat.stackexchange.com (and one for SO). Going to chat.crypto.stackexchange.com does indeed reproduce the shown behavior. – SEJPM Oct 1 at 15:33
• @SEJPM That looks like an answer potato – Ella Rose Oct 1 at 15:37
• @EllaRose I'm on my phone right now and as a matter of principle I don't write answers from my phone. If you want to, you can of course answer with the new knowledge or I'll do it myself in ~2-3h. – SEJPM Oct 1 at 15:38
• I guess we should ask jww if the usual link ( chat.stackexchange.com/rooms/784/the-side-channel ) also works for them before declaring "problem solved". Was any of this helpful @jww ? Or is there still an issue? – Ella Rose Oct 1 at 15:47

From the screenshot, we can see that chat.crypto.stackexchange.com was requested and indeed, requesting this address reproducibly gives the shown error (it also gives a certificate domain missmatch error for me). Whether this a bug or not, I don't know (also I'm mildly surprised that this DNS record even exists).
Now, what you are actually looking for is chat.stackexchange.com as the server hosting does so for all rooms for all stackexchange sites (excluding stackoverflow). If the problem persists with the correct URL, please comment, so we can escalate the issue if neccessary.
